Description

CROSS-REFERENCE TO RELATED APPLICATION
This application claims the priority to and the benefit of Chinese Patent Application No. 202110001859.4 filed on Jan. 4, 2021, the entire contents of which are incorporated herein by reference.
TECHNICAL FIELD
The present disclosure relates to an automobile authentication technology and, in particular, to a vehicle authentication system based on Bluetooth Low Energy (BLE) and fingerprint.
BACKGROUND
With development of science and technology and improvement of the standard of living, popularity of vehicles is increasing. As relatively high-value consumer products used as an alternative means of walking, convenience of vehicle use is increasingly attracting attention from people. At present, unlocking and starting of a vehicle is mostly controlled by a vehicle key, and a vehicle user needs to press a relevant button of the vehicle key near the vehicle to realize locking and unlocking. In the same way, the key needs to be inserted into a locking hole and rotated to realize the starting of a vehicle. This traditional way of unlocking and starting greatly weakens the convenience of the vehicle use.
In order to improve the convenience of the vehicle use, keyless entry systems and one-key starting systems are increasingly applied to medium-sized and luxury vehicles. Using radio frequency technology and vehicle identification code recognition systems, the vehicle user can realize unlocking and starting functions of the vehicle without any operation on the key. However, these two systems still require the vehicle user to carry the vehicle key, and keyless entry and one-key starting functions cannot be realized if the vehicle user does not carry the key.
In recent years, biometric technology has developed rapidly. Since the biometric technology is based on inherent physiological characteristics of a human body for identity authentication, the biometric technology has better security, confidentiality, and convenience, and is widely used in electronic products such as mobile phones, laptops, and tablets. As an advanced recognition technology, there are still many technical problems in applying the biometric technology to a field of vehicles. For example, since the vehicles are often exposed to natural environments such as high temperature, severe cold, wind, and rain, usage environment of the vehicles are more severe than that of electronic products. Therefore, in order to improve the convenience of the vehicle users while ensuring functional reliability, a technical solution that enables locking/unlocking and starting of the vehicle in a variety of ways is required.
The above information disclosed in this Background section is only for enhancement of understanding of the background of the disclosure, and therefore it may contain information that does not form the prior art that is already known in this country to a person of ordinary skill in the art.

The fingerprint authentication controller 120 obtains the fingerprint information from the passenger-side door handle fingerprint identification device, compares the obtained fingerprint information with the pre-stored fingerprint authentication information, and sends the fingerprint authentication result to the central control processor 100 in an encrypted manner. If the central control processor 100 detects a signal of pressing the passenger-side door button of the vehicle, the central control processor 100 sends the detection request message to the fingerprint authentication controller 120.
The vehicle authentication system in some forms of the present disclosure may further include a trunk fingerprint identification device, and the trunk fingerprint identification device may be mounted on the trunk open button, detect the fingerprint information of the vehicle user, and send the detected fingerprint information to the fingerprint authentication controller 120 in an encrypted manner.

If the central control processor 100 receives a detection result that the vehicle key exists, the central control processor 100 executes unlocking the vehicle door or the vehicle starting according to the detection result of the vehicle key. Here, since detection of the vehicle key is well known to a person skilled in the art, description thereof will be omitted.
In addition, if the central control processor 100 receives a detection result that the vehicle key does not exist, the central control processor 100 executes the unlocking the vehicle door or the vehicle starting according to the BLE authentication result from the AVNT smart interconnection device 110.
In addition, if the central control processor 100 receives the BLE authentication result that the authenticated mobile device does not exist, the central control processor 100 executes the unlocking the vehicle door or the vehicle starting according to the fingerprint authentication result from the fingerprint authentication controller 120.
In addition, the vehicle authentication system in some forms of the present disclosure may further include a warning module, and the warning module may be mounted on an integrated display panel in the vehicle.

If none of the vehicle key, the authenticated mobile device, and the authenticated fingerprint information is detected, the warning module displays a logo of “No Fob+BLE+fingerprint”.
Since the exemplary form of the present disclosure provides the vehicle authentication system which controls the vehicle unlocking and starting based on the BLE and the fingerprint, the vehicle can be used more conveniently and safely. For example, since the BLE method cannot be used but the fingerprint method can still work normally when the smart phone is out of power and cannot be turned on, the exemplary form of the present disclosure can prevent the vehicle user from being unable to unlock the door and start the vehicle due to no power of the smart phone. Further, fingerprint recognition may be affected by bad weather or an environment with strong electromagnetic radiation. At this time, the BLE method can make up for these deficiencies.
FIG. 3 is a flowchart of a vehicle authentication method based on BLE and fingerprint in some forms of the present disclosure. As shown in FIG. 3, the central control processor 100 detects whether the signal of pressing the driver-side door button of the vehicle or the vehicle starting button is received at step S1, detects whether the vehicle key exists at step S2 when receiving the signal of pressing the driver-side door button of the vehicle or the vehicle starting button, and sends the detection request message to the AVNT smart interconnection device 110 and the fingerprint authentication controller 120 and checks the detection result of the vehicle key, the BLE authentication result from the AVNT smart interconnection device 110, and the fingerprint authentication result from the fingerprint authentication controller 120 sequentially in a predetermined priority to control the unlocking the vehicle door or the vehicle starting at step S3.
Alternatively, the central control processor 100 can detect the signal of the passenger-side door button of the vehicle. Then, when the signal of the passenger-side door button of the vehicle is detected, the central control processor 100 detects whether the vehicle key exists and sends the detection request message to the AVNT smart interconnection device 110 and the fingerprint authentication controller 120. If receiving the detection result that the vehicle key exists, the central control processor 100 executes the unlocking the vehicle door or the vehicle starting according to the detection result of the vehicle key, executes the unlocking the vehicle door or the vehicle starting according to the BLE authentication result from the AVNT smart interconnection device 110 if receiving the detection result that the vehicle key does not exist, and executes the unlocking the vehicle door or the vehicle starting according to the fingerprint authentication result from the fingerprint authentication controller 120 if receiving the BLE authentication result that the authenticated mobile device does not exist.
Alternatively, the central control processor 100 can detect the signal of the trunk open button of the vehicle. Then, when the signal of the trunk open button of the vehicle is detected, the central control processor 100 detects whether the vehicle key exists and sends the detection request message to the AVNT smart interconnection device 110 and the fingerprint authentication controller 120. If receiving the detection result that the vehicle key exists, the central control processor 100 executes the unlocking the vehicle door or the vehicle starting according to the detection result of the vehicle key, executes the unlocking the vehicle door or the vehicle starting according to the BLE authentication result from the AVNT smart interconnection device 110 if receiving the detection result that the vehicle key does not exist, and executes the unlocking the vehicle door or the vehicle starting according to the fingerprint authentication result from the fingerprint authentication controller 120 if receiving the BLE authentication result that the authenticated mobile device does not exist.

Referring to FIG. 4, processes of the vehicle authentication system based on BLE and fingerprint in some forms of the present disclosure will be described by exemplifying the unlocking of the door using the driver-side door button of the vehicle.
At step S401, the central control processor 100 detects the signal of pressing the driver-side door button of the vehicle.
At steps S402 to S404, whether the vehicle key exists is detected, whether the authenticated mobile device exists is detected, and whether the authenticated fingerprint information exists is detected.
At step S403, whether the authenticated mobile device exists is detected. That is, if the AVNT smart interconnection device 110 receives the detection request message from the central control processor 100, the AVNT smart interconnection device 110 detects the mobile device 150 within 3 m around the vehicle, establishes the detected mobile device 150 through the Bluetooth communication, and obtains the BLE authentication information of the detected mobile device 150. Then, the obtained BLE authentication information is compared with the pre-stored BLE authentication information. If the obtained BLE authentication information coincides with the pre-stored BLE authentication information, it is determined that the authenticated mobile device exists, and if the mobile device is not detected within 3 m around the vehicle or the BLE authentication information of the detected mobile device does not coincide with the pre-stored BLE authentication information, it is detected that the authenticated mobile device does not exist.
At step S404, whether the authenticated fingerprint information exists is detected. That is, if the fingerprint authentication controller 120 receives the detection request message from the central control processor 100, the fingerprint authentication controller 120 obtains the fingerprint information of the driver-side door handle fingerprint identification device 130. Then, the obtained fingerprint information is compared with the pre-stored fingerprint authentication information. If the obtained fingerprint information coincides with the pre-stored fingerprint authentication information, it is determined that the obtained fingerprint information is the authenticated fingerprint information. If the obtained fingerprint information does not coincide with the pre-stored fingerprint authentication information, it is determined that the obtained fingerprint information is not the authenticated fingerprint information.
At step S405, it is determined whether the detection result that the vehicle key exists is received. If the detection result that the vehicle key exists is received, unlocking of the vehicle door is executed according to the detection result of the vehicle key. If the detection result that the vehicle key does not exist, the AVNT smart interconnection device 110 sends the BLE authentication result and the distance information between the authenticated mobile device and the AVNT smart interconnection device 110 to the central control processor 100 in an encrypted manner.
At step S406, it is determined whether the BLE authentication result that the authenticated mobile device exists is received. If the BLE authentication result that the authenticated mobile device exists is received and the distance between the authenticated mobile device and the AVNT smart interconnection device 110 is within 3 m, the unlocking of the vehicle door can be executed. If the BLE authentication result that the authenticated mobile device does not exist is received, the fingerprint authentication controller 120 sends the fingerprint authentication result to the central control processor 100 in an encrypted manner.
At step S407, it is determined whether the fingerprint authentication result that the authenticated fingerprint information exists is received. If the fingerprint authentication result that the authenticated fingerprint information exists is received, the unlocking of the vehicle door is executed. If the fingerprint authentication information that the authenticated fingerprint information does not exist is received, the unlocking of the vehicle door is not executed and the warning module displays the logo of “No Fob+BLE+fingerprint”.
Referring to FIG. 5, processes of the vehicle authentication system based on BLE and fingerprint in some forms of the present disclosure will be described by exemplifying the vehicle starting using the vehicle starting button.

At steps S502 to S504, whether the vehicle key exists is detected, whether the authenticated mobile device exists is detected, and whether the authenticated fingerprint information exists is detected.
At step S503, whether the authenticated mobile device exists is detected. That is, if the AVNT smart interconnection device 110 receives the detection request message from the central control processor 100, the AVNT smart interconnection device 110 detects the mobile device 150 within 1 m±0.2 m around the vehicle, establishes the detected mobile device 150 through the Bluetooth communication, and obtains the BLE authentication information of the detected mobile device 150. Then, the obtained BLE authentication information is compared with the pre-stored BLE authentication information. If the obtained BLE authentication information coincides with the pre-stored BLE authentication information, it is determined that the authenticated mobile device exists, and if the mobile device is not detected within 1 m±0.2 m around the vehicle or the BLE authentication information of the detected mobile device does not coincide with the pre-stored BLE authentication information, it is detected that the authenticated mobile device does not exist.
At step S504, whether the authenticated fingerprint information exists is detected. That is, if the fingerprint authentication controller 120 receives the detection request message from the central control processor 100, the fingerprint authentication controller 120 obtains the fingerprint information of the vehicle starting button fingerprint identification device 140. Then, the obtained fingerprint information is compared with the pre-stored fingerprint authentication information. If the obtained fingerprint information coincides with the pre-stored fingerprint authentication information, it is determined that the obtained fingerprint information is the authenticated fingerprint information. If the obtained fingerprint information does not coincide with the pre-stored fingerprint authentication information, it is determined that the obtained fingerprint information is not the authenticated fingerprint information.
At step S505, it is determined whether the detection result that the vehicle key exists is received. If the detection result that the vehicle key exists is received, the vehicle starting is executed according to the detection result of the vehicle key. If the detection result that the vehicle key does not exist, the AVNT smart interconnection device 110 sends the BLE authentication result and the distance information between the authenticated mobile device and the AVNT smart interconnection device 110 to the central control processor 100 in an encrypted manner.
At step S506, it is determined whether the BLE authentication result that the authenticated mobile device exists is received. If the BLE authentication result that the authenticated mobile device exists is received and the distance between the authenticated mobile device and the AVNT smart interconnection device 110 is within 1 m±0.2 m, the vehicle starting can be executed. If the BLE authentication result that the authenticated mobile device does not exist is received, the fingerprint authentication controller 120 sends the fingerprint authentication result to the central control processor 100 in an encrypted manner.
At step S507, it is determined whether the fingerprint authentication result that the authenticated fingerprint information exists is received. If the fingerprint authentication result that the authenticated fingerprint information exists is received, the vehicle starting is executed. If the fingerprint authentication information that the authenticated fingerprint information does not exist is received, the vehicle starting is not executed and the warning module displays the logo of “No Fob+BLE+fingerprint”.
